Benefits of technology

The patent describes an apparatus for folding printed sheets, which includes two crease rollers and a spacing device that creates a nip space between them. A movable crease blade is also included to push the sheets into the nip space. This apparatus can be used in a booklet maker to create booklets by collecting sheets and engaging them with the crease blade. The technical effect of this invention is to provide a more efficient and precise method for folding printed sheets, resulting in booklets with better quality and consistency.

Problems solved by technology

Due to variations in surface roughness of sheets and the print material, the friction between the outer sheet and the underlying sheet may not be sufficient.
Therefore, the top sheet may be torn or otherwise damaged as it passes through the crease rollers.
Such tear off damage typically leads to a jam which requires clearing by an operator and significantly slows the booklet making process.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to automated booklet makers, in which sheets forming a booklet are folded by passing through a pair of crease rollers.[0003]2. Brief Discussion of Related Art[0004]Booklet makers are well-known devices for forming folded booklets which are stapled along the crease thereof. It is becoming common to include booklet makers in conjunction with office-range printers. The word “printer” as used herein encompasses any apparatus, such as a copier, digital copier, bookmaking machine, facsimile machine, multifunction machine, etc. which performs a print outputting function for any purpose. In basic form, a booklet maker includes a slot for accumulating processed sheets, as would be produced by a printer. The accumulated sheets, forming the pages of a booklet, are positioned within the stack so that a stapler mechanism and complementary anvil can staple the stack precisely along the intended crease line. The creased and sta...
